Read-only files

Last modified: 26 March 2024

If a file is read-only, it is marked with the closed lock icon the Locked icon in the status bar. If a file is writable, it is marked with the open lock icon the Unlocked icon.

Library files in IntelliJ IDEA are normally read-only. For such files, you will not see the lock icon in the status bar. IntelliJ IDEA applies Reader mode to library files by default.

Toggle the read-only mode on and off

  • Open a file in the editor and click the lock icon the Locked icon/the Unlocked icon in the status bar.

  • Alternatively, select a file in the Project tool window (Alt01), go to File | File Properties in the main menu and click Make file read-only.

    Making file read-only

If a read-only status is set by a version control system, it is suggested that you use IntelliJ IDEA version control integration features. For more information, refer to Version control.
